ELEVATOR'FOR CORN-SHELLERS. I

SPECIFICATION forming part of Letters Patent No. 355,212, dated December23, 1886.

Application filed January 29, 1886. Serial No. 190,214. (No model.) I

To all whom it may concern.-

Be it known that I, OYRUs RoBER'rs, of Three Rivers, in the county ofSt. Joseph and State ofMichigan, have invented new and usefulImprovementsin Elevators for Corn-Shellers; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, which form a part of thisspecification.

This invention relates to a new and useful improvement in elevators forcombinedhuskers, shellers, and separators; and the invention consists inthe improved construction and arrangement of the mechanism for carryingaway to a place of deposit the different products obtained by theseparation. The object of the improvement is to enable the operator tocarry these products at his will in any desired direction to a placeconvenientforfilling them in bags or depositing them otherwise, all asmore fully hereinafter described and claimed.

In thedrawings which accompany this specification, Figure l is a sideelevation of a combined corn, husker, sheller, and separator. Fig. 2 isa cross-section of the tail end of the machine. Fig. 3 is a detachedperspective view of the hinged platform upon which the lower end of thecob-carrier is supported. Fig. 4 is a detached perspective of thecob-carrier. Fig. 5 is a detached perspective View of. the cob-spout.

The drawings represent a known type of machine arranged to husk, shell,and separate corn. In this machine A represents the elevator forcarrying off the clean corn. B isthe conveyer which carries the corninto the lower end of this elevator, and G is the dischargespout of theelevator. This discharge-spout is made in two sections, the upper onebeing stationary and connected with the discharge endof the elevator,while thetitower section is movable by being connected to the uppersection by means of a universal joint. This joint consists of the hangerD, which is secured to the upper end of the movable section of thedischarge-spout, and ispivotally hung from a loose collar, E, whichlatter is, swiveled onto 50 the lower end of the stationary section ofthe dischargespout. All these parts are so arranged that the movablesection of the discharge-spout may be easily turned by the operator inany direction, so as to deliver the corn to either side of the shellerinto a wagon I or to ruin it into gunny sacks, if desired.

G is the cob-carrier, placed at the tail end of the machine to receivethe cobs discharged from the machine and carry them to a place ofdeposit. This cob-carrier is made shifting, so as to deliver the cobs oneither side of the sheller, and,when not shelling in husk, to deliverthem also in the rear, if desired. To this end the cob-carrier isarranged as follows:

H is a platform, hinged to the tail end of 6 the machine in anyconvenient'manner, and provided with suitable hangerssuch as the strapsIforsuspending it at different heights above the ground. Upon thisplatform is journaled in boxes the shaft J, which is pro- 7C vided atthe outer end with a chain-wheel, K, and at its inner end with abevel-pinion, L, which meshes with the bevel-wheel M. This latterrevolves on a vertical shaft, 0, secured near the middle oft-heplatform,and also serves 7 5 as a pivot for the arm N,which is sleevedupon its lower end, so as to rest on the platform The outer end of thearm N is provided with boxes or bearings P, in which the box R, on thelower end of the couveyer-trough Q, is re.- 3 movably secured, so as toform a pivotal support for said trough. TheboX R forms the bearing forthe shaft to which the drive-wheel S of the conveyer-belt T and thebevel-pinion U are secured. 85

In practice the motion for operating the conveyer-belt is applied to thechain-wheel K, and is derived by suitable chain-gearing (not shown) fromthe machine, and by means of the intermediate connections described itis transo mitted to the wheel 8, over which the conveyer-belt passes andcarries the cobs to the discharge end of the cob-carrier. It will beseen that the cob-carrier can readily be shifted in any direction ateither side of the sheller, 5 and thefree end of the conveyer-trough canbe raised or lowered by supporting it at the desired height, by means ofsuitable braces, from the ground. All the parts are thus kept out of theway of the flying husks of the corn, which, too as usual in suchmachines, are blown out at the tail end above the cob-spout.

The advantage of my improved cob-carrier is that its gear fortransmitting motion to the conveyer-belt is very simple, and is notliable to be obstructed by any debris which may find its way out of thelower end of the conveyertrough, as the gear is not underneath it, but

- is all placed to one side thereof. Another advantage is that whenshelling wet corn, when the wind cannot carry the husks so far, thecob-carrier can be moved to theposition shown in Fig. 2, where it isentirely out of the way of the husks. The adj ustability of the platformH permits of its being raised any distance required above the groundwhen the machine has to be transported, or for the purpose of keeping itout of the mud.

To prevent the cobs on their way to the cobcarrier from getting chokedup in the cobspout, I construct the cob-spout V in a novel manner.Instead of constructing it in the usual form of a hopper with a bottomdischarge, I make it more in the form of a V- shaped trough havinginclined walls for directing the cobs toward the center and to adischarge-opening, W, formed in the bottom and inclined walls of thespout, through which the cobs can pass out freely in the longitudinaldirection of the machine. In this manner the cob-spout forms the tailend.

discharge-opening get choked, the cobs would still be discharged byfalling over the tail end of the spout.

What I claim as my invention is- 1. The combination, with the elevatorA,

having stationary part 0 of the spout rigid.

therewith, of the loose collar E, swiveled onto the lower end of saidpart 0, the hanger D, pivotally hung from said collar, and the movablepart 0 of the spout secured to and supported by said hanger,substantially as and for the purpose specified.

2. The combination, with' the shoe, of the cobspout forming the tail endthereof, said spout being in the form of a V-shaped trough, the walls ofwhich incline toward the tail end of the machine, and provided with acentral discharge-opening through the bottom and said
